Sensor Calibration
The Calibration Procedure can be considered as a learning and optimisation process of
the sensor. The DLS2 gathers the characteristics of the line. Properties like line width,
contrast on left line edges, contrast on the right line edge and line colour are measured
and stored. The line must fulfil certain quality criteria
(contrast, dimensions etc.)
to be
recognised as a line. If these criteria are not fulfilled the calibration will fail and an error
pattern will appear on the LED-Display.
The calibration is started with the selection of the operation mode (ref. to
section 8
).
Press the key that complies with your application:
Line Detection (centre of line)
Pattern Recognition
Line Edge
Detection
Hologram Detection
Material Edge Detection
After the operation mode choice start the calibration by pressing the
key for
longer than half a second
. During the calibration all LED will flash.
Calibration Result
LED-Display
If the calibration was successful, the sensor will
display the actual line or edge position in relation
to the sensor detection range.

edge detection
At unsuccessful calibration the sensor will display
an error pattern. Even and odd LED will flash
alternating.
After a successful calibration and a test run the object data (calibration data) can be
stored as a profile (ref. to
section 9
„Profile Management“)
